Asked this over in the video production subforum, but thought I'd throw it out here. I've noticed FCPX has slowed down it's opening sequence significantly on my nMP (25 seconds). I'm on a dual monitor setup, 8 core 32gb, and my current project is maybe 20-30 seconds long. Any ideas? EDIT: OK, now I'm just confused. I created a new library and hid all the others and moved them out of the movies folder. Still had the hang. However, out of desperation I pulled my SD card from my camera and plugged it back in and presto- FCPX starts up in 2 seconds now. Mind you, I never imported from the card- I always copy over any media to my HD, then import to FCPX. EDIT 2: One more piece to the puzzle before I quit for the night. The SD trick I mentioned earlier only works for the first few minutes- then FCPX returns to the 25 seconds startup unless I eject and reinsert the SD card. I've deleted all my libraries and events, I've deleted the 3 pref files, nothing. I've created a test account, and FCPX runs lightning fast on it. Guess I'll reinstall while I sleep, but I'd love if anyone had any other advice!
